      <title>CVE-2022-49917 — ipvs: fix WARNING in ip_vs_app_net_cleanup()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-49917</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;ipvs: fix WARNING in ip_vs_app_net_cleanup()&lt;/p&gt;
&lt;p&gt;During the initialization of ip_vs_app_net_init(), if file ip_vs_app
fails to be created, the initialization is successful by default.
Therefore, the ip_vs_app file doesn&amp;#39;t be found during the remove in
ip_vs_app_net_cleanup(). It will cause WRNING.&lt;/p&gt;
&lt;p&gt;The following is the stack information:
name &amp;#39;ip_vs_app&amp;#39;
WARNING: CPU: 1 PID: 9 at fs/proc/generic.c:712 remove_proc_entry+0x389/0x460
